To all whom it may concern:

Be it. knownthat 1;, Gnonen Enwoon Coon, a oitizen' of the UnitedStates, and a resident of the city of New York, horoughof Brooklyn, inthe county. of Kings and State,

of New York, have invented a: new and Improved Geanshiftin Device ofwhich the is a full, ear, mid exect descripfollowing lion.

The. invention relates to automobile gear sets of the selective type,and its object is toprovide a-new andimproved gearshiftingmdevicesmore.especially. designedhfor use in the powertransmissionof automobiles,

autos-trucks" and otherpower driven vehicles,

I and arranged to enable the driver to readily change the speed orreverse selectively as needed at the time and without first shifting toany other speed.

In order-to accomplish the desired result use is made of a change speedgear set provided with a shifting member. manually controlled meansconnected with the said shifting member to move the latter nto see, g

on the coimtershait 37 o n'naled 1n the hoxi lective position,- aclutehpedal, and a con- ;nection' connecting the clutch pedal with the saidshifting member ;to move the latter .fil'om selective, into actuatingposition,

The pedal 20 oftlie clutch opera-ting de vice is fulcrumed on a shaft 21journaled in brackets 22 attached to or forming part of the forward endof the box 2311f the change speed gear set ()n the shaft 21 is seeured ashifting fork 2l engaging a shift- ,mg collar 25 on the movable clutchmember 26 ofa clutch 27 adapted to connect the engine or crank shaftwith the transmission sha'ft29 in the usual manner. The transmissionshaft 29 extends into the box 23 and on the end of the transmissionshaft 29is secured a drive gear wheel 35 in mesh with.

theeountershaft drive gear wheel 36 secured 23. 'Qn the countershaftB'?is secured a .pinion 38 in mesh with an intern ediate pinion 39journaled in the box 23 and adapted to be to engage a gear wheel 45secured on the counte'rshaftfl? on which is also secured a' gearWheelAGjinterlnediute the gear wheels 36V and 45. The gear wheel 46 1sadaptedto be engaged by a gear Wile-GL4? mounted to turn with and toslide lengthwise on the drive shaft 41,, and r11? said gear wheel 4? isprovided with a clutch member v4d adapted to engage a clutch member 4-9arrangl-ii'l on the drive gear wheel secured to the transmission shaft29 as previously explained.

The shifting forks 52, 53 are provided witi'i travel up and down,

cylinder (33 mounted to slide longitudinally on a piston 6% having itsfixed )lSiZOll rod attached to a bracket 66 exten ing from the top ofthe box 23. The lever 60 and the bracket (32 extend through a slot (37formed in the top of the box 23. A spring 68 is interposed between thepiston (it and the rear head (59 of the cylinder 63 with a View to movethe cylinder 63 in a rearward direction, as hereii'iatter my. efullyexplained.

The top of the cylinder 3 is provlded with transverse guideways T0 inwhich is mounted to slide a cam plate 71 pivotally connected at one sidewith a link 72 conuectedv by a ball and socket joint 73 with an arm 74secured on a shaft 75 mounted in the steering column and terminating ina pointer handle 77 indicating on a dial (8, as plainly shown in Fig.-t. The dial is provided with a grguluation indicating reverse, lirstspeed, neutral second" speed and higlf speed. .Thus the driver impartinga swii'iging motion to the handle 77 turns the shaft more or less toshift the cam plate 71 corrcspondiugly in a transdial 78. As shown inFig. 1, the pointer handle 77 is in neutral position. The top of the camplate 71 is provided with cams 80, 81, 82, 88 and 84, preferably markedwith indicating characters corresponding to those on the. dial 78. Thecams 80, 81, 82, 83 and 84 are spaced apart in a transverse direction,and on shiftin" the plate 71 transversely any one of the sai cams can bemoved into the path of'a friction roller 85 journaled in a'.'lepending.arm 86 on a bar 87 pivotally co'nilBCtBd at its forward endwith an arm 88 cured on the pedal shaft 21.

The cam (see Fig. 10) is in the form of an -incline for the frictionroller to Thecam 81 (see Fig.

9) isin the form of a recessed lug adapted to be enga d by the frictionroller 85 to move the p ate '71 andwith it. the cylinder 63 in a forwarddirection, as hereinaftel" more fully explained. The cam 82 (see Fig. 8)is in the co11ibined,f01'in of an incline and recessed lug for thefriction roller 85 to'travel up the incline-and. engage thev re cesswith a view to move the plate 71 and the cylinder 63 forward.- The cam83 is in the form of an incline for the friction roller 85 to travel upand down. The cam 84 is similar to thecam 81, that is, is in-the formofa recessed lug for engagement by the friction roller 85. I

The forward end of the cam plate 71 is provided ith brackets ,90 sup)orting two transversely extending g'uide'rods 91 and 92 on which'ismounted to slide in a transverse direction a yoke 93 engaging the upperrectangular end of the shifting lever 60. The

'- hereinafter more fully explained? osition, as I of the arrow as aswingin movement is given..- to the lever 60 n one lrectlon, and whenthe cam plate 71 moved from neutral posi tion in t 1e inverse directionof the arrow then a swinging movement is given to the lever 0 in theopposite direction. On shifting the cam plate 71 in either of thedirections mentioned, the corresponding cams '83, 84 and 81, 80 arelnovcd'into the path of the friction roller 85 on the bar 87. Theextreme upper portion of the lever 60 extends into the opening 100 of anH-plate 101 attached to a bracket 102 rising from the box 22- of thechange speed gear set. It is understood that the upper end of theshifting lever (it) is guided to the proper positions in the opening 100of the H-plate 101 to insure proper meshingof the speed changing gearwheels 1t). 17 with the gear wheels 35), 4-5 and as and the clutchmembers-l8, 49. It is understood that the transverse swinging movementof the shifting lever (50 is limited by theside walls of the opening 100in the H-plate lOI-dur-ing the transverse shifting of the cam slide 71in either direction of the arrow .1, and the corresponding springAH or95 is compressed during the further movement of the slide 71 intoselective posit-ionf v The rear portion of the bar 87 extends through anopening in a vertically disposed catch 111 mounted to slide up anddownin suitable guideways 112 arranged on brackets 1123 rising from the box23'of the chan e )eed ear set., \Vithi'n the o )611'- The outer ends ofthe rod llti' are connectedwith s rings 117 fastened at their lower endsto the Racket-113 to exert a dmvnward res sure on the catch 111. Thebottom 0 the catch 111 is adapted to engage any one of three steps orshoulders 120, 121 and 122 of a step plate 123 secured tOzl'llG head(it) ot' the cylinder ()3 to lock the cylinder in any one of itsadjusted positions. The rear portion of the rod 87 is adapted toerigagethe' under side of the friction roller to lift the catch 111 witha view-to disengage the same from any one of the steps 120,121 or 122.as

The forward movement of" the cy'li rider 63 is controlled by the driverpressing the peda l 20 in crammed- -di-rect-ion, and the return movementof'the cylinder 63 is governed)?? its spring 68; andin' order tocl1eck-theti'cf tion" of the spring 68 use-is'lnade of "11 re? the bar87-- 1 during 8", then the tarding means such, for instance, as shown inFig. 5. The cylinder 63 is filled with glycerin, oil or other suitableliquid, and a by-pass 130 is formed in the cylinder to connect theopposite ends with each other. The by-pass 130 is provided with a valve131 adapted to open during the forward movement of the; cylinder 63 toallow the liquid totlow unohstructedly from the rear end of the cylinderinto the front end thereof, but when the cylinder 63 moves rei'trwardlythe valve 131 closes theihy-pass 130 at the forward end. and the liquidin the forward end of the cylinder 63 now passes by way of a cleat hole132 into the by-pass and by way of the latter to the rear end of thecylinder 63. As the flow of the liquid the return movement ofthecylinder (i3 is comparatively slow, it is evident that the act-ion ofthe spring 68 is checked and with it the return movement of the cylinderThe operation is as follows:

'When the several parts are in the neutral position shown in Figs. 1, 2,3, 4,8 and lever 60 is in midway position in the opening 100 ofthe'H-plate 101, the friction roiler 85 is in engagement with the cam82, and the catch. 111 is in engagement with the step 121 and hence thecylinder 63 w is held against either forward or backward-i movement,with the gears of the gea-igjsetin,

the neutral position shown in Figland the lower end of the lever 60midway between the notched lugs 56 and 57', as shown in Fig. 11. Whenthe driver desires tothrow in the change speed gear, say into firstspeed,

he turns the handle 77 to the mark 1 on the dial 78 whereby the camslide 7 1 is shifted in the inverse direction ofthe arrow w until thecam 81 is in the path of the friction roller During this movem I It,ofithe cam slide 71 the'latter imparts-a inging motion to the shiftinglever ti flf-wherehy the upper end thereof moves into. the middle of theright handle of the H-plate 101 and the lower end of tie lever 60 movesinto engagement-with the notched lug 56. The

driver now'presses the pedal 20iorwardwhereby a forward movement isgiven to the friction roller 853 thereof 4 o engagement with the cammoyes the same forward and with it. cum slide 71 and thegcylinder 63,which ,ter carriesthe leverlil) bodily along and now Int 8 wheel 40 toslide, forward and into mesh with the first speed gear wheel 45. Theoperatornow. releases the i View to rotate the transmission shaft, thecounter-shaft, and the 38, 45 and 46 mountedthereon.- The rotary motionof the gear wheel 45 is now transmitted to the gear wheel 40 and by thelatter the lever (30 moves the shifting pedal 20 to throw in theclutch.v

gear wheels, gaging the step 122, it being to the drive shaft- 1] torotate the latter at first speed. During-the forwardmovement of thecylinder Gi B Hthelocking catch 111 drops from the step 121 into thestep 120 by the action of its springs 117 thus locking the cylinder inforward osition and thereby holding the parts'in iii-st SJBGd position.During'the release of the pe al 20 the bar 87 returns to its normalposition and-its friction roller 85 moves rearwardly out of engagementwith the cam 81.

\Vhen' it desired to change from first speed to say second the handle 77from the 1 mark to the mark. on the dial 7 8 whereby the cam slide 71 ismoved in the direction of the arrow as until the cam in the path of thefriction I llllllg the forward movement of the pedal the bar 87 is movedforward and its friction roller 85 now travels up the cam 83 thusimparting an upward swinging motion to the bar S7 whereby the catch 111is raised out of engagement with'the step 120 to allow the cylinder 63to slide slowly rearward by the action of its spring 68 and retarded, bythe slow n'iovement of the liquidilowing from the front end of thecylinder- 203a the rear end thereof. During this rearward movement ofthefcylinder 63' the shifting lever 60, the shifting fork 52- and thegear wheel 40 are carried along whereby the gear Wheel 40 moves out ofmesh with the gear wheel 45.

When the upper end of the shifting lever- 60 reaches a middle positionin the right hand leg of the H-plate 101 the previously compressedspring 94 imparts a sliding mos tion to the y0ke93 in the direction ofthe arrow 03 whereby a swinging motion is given carried along and 'with'ill the fork53 and the gear wheel 47. The latter now moves intoengagement with the second speed gear speed, the driver turns wheel 46.The driver now releases'the pedal 1 I -20 to throwthe clutch into activepositionwith a view to rotate the transmission shaft i 1 20, therountershaft 37 and the .gear' wheels 38, 45 and 46 mounted thereon.The-rotary mot-ion of the..+;econd gearwheelAG is now. transmitted tothe gear Wheel-I47 and the 41 to rotatethe latter 'atsecdrive shaft ondspeed. I The return gin cylinder 63 limlted hyjh ex t of I the Inderstood't'hat the catch 111 was lifted sufiiciently high by the bar 87to clear the stepr121 by the-action of the can: 83 on theharB as shownin Fig.

n hatch E 11 en- 7 85 andthe spring 95 is placed under tension.

The driver now presses the pedal 20 in a forward direction to stop thecmlntershaft '37 and to cause the friction roller 85 to en-' gage'thecam 84 and pull the cam slide 71, the cylinder 63 and the shifting lever60, the shifting fork 53 and the gear wheel 47 forward whereby thelatter moves out of mesh with the gear wheel 46, and its clutch member47 moves into engagen'lent with the clutch member 49 of the drive gearwheel 35. During the forward movement of the cylinder 63 the'sprin 68 isplaced under tension and the catch {11 snaps first into the step'121 andthen into the step 120 to lock the cylinder (33 against rearwardmovement.

When it is desired to change from high speed to say second speed orfirst speed or to neutral position, it is only necessary for the driverto first swing the handle 77- to the corresponding mark '2, 1 or N onthe dial 7 8 to correspondingly shift the cam slide 71, and then thedriver presses the pedal 20 with the result above explained, after whichthe pedal is again released.

lvhen it is desired to change from neutral, lirst, sccond oi high toreverse position the driver turns the handle 77 to the mark R i on thedial 78 whereby the cam slide 71 is to remain there. 'lhc. shiftingofthe cam slide 71 causes a transverse swinging of the lever 60 to engagethe latter with the notch 56 and during the rearward movement of thecylinder (it-tthe lever (30, the shifting fork 52'and the gear wheel H)are ('iUl'lO-tt along to move the gear wheel rtlintomesh with theintermediate gear wheat 39. The pedal. 20-is next released to rotate thecountersha-ft which by the gear wheel 38, the intermediate gear wheel 39and the gear wheel 40 rotates-the drive shaft in the re- \-e|.'se"direction to that of the transverse shaft. l/Vhen thepedal 20 is nextreleased the bar 87 returns to normal position. t )m the forcgoingitwill be seen that thedriver in order to change from neutral pedal 20 thetion, it is only necessary for the driver to move the handle 77 to thecorresponding mark on the dial 783, then press the pedal 20 and finallyrelease the same. As the handle 77 is preferably located at the steeringwheel it is within easy reach of one hand of the driver.

It will be noticed that by the a-rran ement described, useis made of amanna ly controlled selecting mechanism. and .ii elutoh pedal controlledactuating mechanism, of which the selecting mechanism is set'into adesired selected position by the driver manipulating the handle 77correspondingly, and thc saidzn-tuating mechanism co acts with the saidselecting mechanismto change the gear sci according to the selectedposition.

\Vhcn changing the gear set to first speed or high speed. the pressingof the clutch pedal 20 moves the cylinder (33 ot' the achrating'mechanism forward by the pressure applied by the foot of the drivcr onthe said pedal (scc Figs. (3 and 9) and in changing the gear set tosecond or reverse the cylinder (33 ot' the actuating mcchanism is movedrearward by the pressure of its spring'GS after the cylinder is releasedby the catch 111 on the driver prcssing'the clutch pedal it) forward. v;

It will also be noticed that the driver can press-thc clutch pedal 20forward toilisconncct the motor shaft from the transmission shaft nomatter in what position the gear set is in at the time andwithoutaifccting the position of thc gear set.
